Yeah, I looked it up when it happened. Apparently they have some kind of agreement with Getty Images where Getty made them get rid of that - and the "search for similar" feature as well - apparently they believed that those features were the primary reason for people "stealing" their stuff - copyright issues and such. Fortunately you can just right-click to get the URL... extra step, and stupid, but it works as a workaround, so I'm honestly not sure why they bothered in the first place.

That first image, though... those skeletons. For some reason the picture is more funny to me than it is scary. Neat train, though
